These links are from several years ago, for old PySide rather than new PySide2. I am surprised it is still the case: is this a bug, has it been reported on the Qt bugs site to the PySide2 people?

The OP claims on stackoverflow (better to have copied the post here than just reference it):

If the imported package is PyQt5, it can work ! But if i replace PyQt5 with PySide2, it can't work again

:)

Which is why I want to verify he is running both from the same directory....

Then it really does sound like it's having trouble finding the file. And I still don't get why that differ from PyQt, unless you are running the PySide from a different folder.

FWIW: Try changing that guy's code so that you keep the original QMainWindow::centralWidget(), add a Q[HV]BoxLayout onto it, and add your QLabel onto that; and maybe put in some explicit sizes while you sort it out. It's just possible you have a layout issue. Also try label.setScaledContents(True). I'm not sure why it works from PyQt but not from PySide2.

Yes, i put the py script and cat.jpg in the same folder, even though i pass the full path of cat.jpg, the window is still empty, please see the sreenshot (i.postimg.cc/ZqGW6xpz/image.png)

Unless cat.jpg is in the same folder as where you start your python script, that won't work.
